This device’s patented needle cartridge features 33-gauge stainless steel, gamma sterilized needles that oscillate as high as 120 revolutions per second (7,200 rpm), allowing increased maneuverability for operators. In addition, the unit’s patented radiofrequency identification (RFID) system provides unparalleled and accurate needle penetration depth by automatically and consistently calibrating the needle cartridge with the device. Proprietary Advanced Oscillating Vertical Needle (AOVN) technology mechanically calibrates the motor speed, pressure and penetration, allowing the operator to perform scar treatment at 3.0 mm, which was not previously achievable in a microneedling device.
“Not only is Dermapen 4 loaded with the latest technology, clinical results include increased procedural efficacy, which promotes patient safety without the usual risks associated with other microneedling devices or rollers,” stated Tijion Esho, M.B.Ch.B., M.R.C.S., M.R.C.G.P., a cosmetic surgeon in London, U.K.
Dermapen is a go-to treatment modality for skin rejuvenation that works with all skin types, said Sheila Nazarian, M.D., a plastic surgeon in Beverly Hills, Calif. “When I started my practice, a lot of my patients had darker skin types, and I am also pigmented. Some laser-based devices burn the skin, and when pigmented skin burns, we turn brown. So, I was looking for something mechanical that I could offer my darker skin type patients that wouldn’t produce pigmentation disorders. It also
does a great job on acne scars.”
“My first reaction was ‘wow’; it is like having a Knight Rider in your hand,” Dr. Esho commented. “You have so much precision over a greater area. I fell in love with it, not just because of the design, but because of how easy the glide was and how powerful it is in comparison to other devices.”
According to Andrew R. Christie, M.D., a medical trainer and health science specialist in Paris, France, “Dermapen 4 is the fastest automated pen on the market. It has 1,920 microchannels per second. Nothing beats that. You can work a lot faster, and it makes for a more profitable procedure. Ultimately, the speed of treatment also makes it more comfortable for the patient. I can treat a full face in around four minutes and maximize the use of puncture channels that I’m actually working with, as well.”
